Specification of Letters Patent.

Patented Dec. .19, 1911.

Application filed December 22, 1910. Serial No. 598,837.

To all whom it may concern.

Be it known that I, ADOLPH G.W\VESTBY, a citizen of the United States, residing at Porter, in the county of Yellow Medicine and State of Minnesota, have invented certain new and useful Improvements in Beating and Mixing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved beating and mixing machine, especially adapted for use in whipping cream, mixing batter and the like, and is provided with interchangeable agitators and driving means to meet various requirements and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in front elevation showing the improved device secured to a table top and with the agitator projecting in a receptacle which is indicated in section; Fig. 2 is a plan view of the improved device removed from the table top; Fig. 3 is a view partly in side elevation and partly in section taken on the line m m of Fig. 2; Fig. 1 is a. detail view of one of the so-called beater blades, in section, taken on the line 00 m of Fig. 1, on an enlarged scale and turned into a different position; Fig. 5 is a View corresponding to Fig. 3, with the exception of the driving device, which shows a crank in place of the rack and pinion shown in Figs. 1 and 2; and Fig. 6 is a View in side elevation showing a modified form of the agitator.

The numeral 1 indicates a standard in the form of an upright bar, the upper end of which is bent laterally to afford a supporting arm 2, and the lower end of the standard 1 is provided with a base plate 3 having rigidly secured thereto an underlying and laterally spaced jaw 4. The base plate 3 and jaw 41: are adapted to embrace the edge portion of the table top 5 or any other suitable support. Mounted in the horizontal portion of the jaw 4 is an upwardly projecting thumb screw 6 having swiveled thereto a clamping plate 7 which works between the base plate 3 and jaw 4 and cooperates with the base plate 3 for clamping the standard 1 onto the table top 5.

Depending from the under side of the supporting arm 2 and near the free end thereof, is a shaft 8 terminating at its upper end in a small cone bearing 9 mounted in a bearing seat 10 formed in the under side of the supporting arm 2. The shaft 8 is held properly alined by means of a depending spider bracket 11, the legs of which are sooured to the under side of the supporting arm .2 on either side of the seat 10, and the intermediate portion thereof is provided with a seat 11 in which is seated the shaft 8. Secured to the shaft 8, by threaded engagement, is a beveled pinion 12 and an adjusting nut 13 located, respectively, above and below the intermediate portion of the bracket 11. The beveled pinion 12 rests on the bracket 11 and holds the shaft 8 against downward movement, and the nut 13 engages t-he underside of the bracket 11, to prevent any upward movement of the shaft 8. As is evident, by adjusting the beveled pinion 12 and nut 13 on the shaft 8, the cone bearing 9 may be properly adjusted with respect to the seat 10. Below the adjusting nut 13, the shaft 8 is provided with a balance wheel 14, and the extreme lower end of the shaft 8 is further provided with an internally threaded coupling sleeve 15, for detachably holding different forms of agitators. Meshing with the beveled pinion 12 is a beveled gear 16 loosely mounted on astud shaft 17 secured to the supporting arm 2 directly over and at right angles to the shaft 8. One end of the stud shaft 17 is reduced to form a shoulder 18 and the reduced end thereof is screw-threaded and passed through a. seat in the supporting arm 2, and a nut 19 is applied to the projecting threaded end thereof for clamping the arms 2 between the shoulder 18 and the nut 19. The outer end of the stud shaft 17 is provided with an inwardly beveled head 20 countersunk into the outer hub portion of the beveled gear 16. The extreme outer end of the hub portion of the bevel gear 16 is reduced to form a shoulder 21 and the reduced portion thereof is provided with screw threads for detachably holding a pinion 22, the outer hub portion ofYwhich terminates in a headed stud 23 for guiding a rack, which imparts motion to the pinion 22.

The rack for driving the pinion 22 is preferably constructed, as shown, from a pair of vertically disposed and laterally spaced inner and outer elongated plates 24 and 25, respectively. These plates are detachably secured one to the other and spaced apart from each other, at their marginal edges, by means of interposed washers 26 and screws 27 passed through the plates 24 and 25 and the interposed washers 26. Laterally projecting from the outer face of the plate 24 is a row of alined pins 28 centrally located between the upper and lower edges of the plates 24 and 25 and extends not quite the full length thereof. The outer projecting ends of these pins 28 constitute rack teeth for engagement with the pinion 22 and their inner ends are screw-threaded intoboth of the plates 24 and 25 and help to hold the same in their proper spaced relation to each other. The plate 24 is provided with an endless channel or track 29 for receiving the headed stud 23 which guides the rack with respect to the pinion 22. The endless channel 29 extends completely around the entire row of pins 28 and is formed by cutting away the intermediate portion of the plate 24 between the outer edge portion thereof and the pins 28. This channel 29 is of such width as to receivethe neck portion of the headed stud 23 and the head thereof works between the laterally spaced plates 24 and 25 and between the spacing washers 26 and row of pins 28.

The rack receives motion from an oper ating lever 30 pivotally secured at its lower end to the standard 1, by means of a short nutted bolt 31, and at its upper end is connected to the plate 25 by means of an arm 32, preferably integrally formed with the plate 24 and is pivotally connected at itsfree end to the upper end portion of the operating lever 30, by means of a short nutted bolt 33.

By operating the lever 30, it is evident that the momentum imparted to the rack will cause the same to travel in an elongated circuit, being guided in its course by the headed stud 23 working in the endless track 29, and the teeth of the rack are so arranged as to travel completely around the pinion 22, thereby imparting a continuous rotary motion to the agitator.

In Fig. 1 is shown an agitator especially adapted for whipping cream and the like and is used in connection with the rack and pinion where it is necessary to drive the agitator at a comparatively high speed. As shown, this agitator is in the form of a pair of reversely acting and horizontally alined blades 34 loosely mounted one in each end of a horizontally extended spindle 35 rigidly secured at its intermediate portion to the lower depending end of a shaft 36 vertically alined with the shaft 8 and detachably connected thereto, at itsupper end, byscrewthreaded engagement with the coupling sleeve 15. The beater blades 34 have their horizontal edges beveled, as best shown in Fig. 4, and are adapted to rotate on their horizontal axis at the same time they are rotated in a horizontal plane around the shaft 36 under the action 'of the driving mechanism.

In Fig. 5 is shown a crank 37 detachably secured by threaded engagement with the hub portion20 of the bevel gear 16 and is adapted for use as a substitute for the rack and pinion when it is desired to impart a comparatively low speed to the agitator as is required in mixing batter and the like.

In Fig. 6 is shown a modified form of agitator used in connection wit-h the crank 37 and is especially adapted for use in mixing batter. This modified form of agitator is in the shape of a rod 38 having its upper end detachably connected by screw-threaded engagement to the coupling sleeve 15 and its lower end is first bent laterally and then upon itself, so as to project transversely of the connected end of the agitator.
